Secure Data in Wireless Sensor Network by Using DES

The main goal of sensor networks is to provide precise information about a sensing field for an extended period of time. The emergence of sensor networks is one of the dominant technical trend has posed challenges to explorers. As sensor networks may interact with sensitive data and operate in hostile insecure environment, it is clear that these security concerns can be addressed from the basic system design. These networks are likely to be composed of hundreds, and potentially thousands of small sensor nodes, functioning independently.
